Welcome to this active site. Each week I am going to present to you an endgame position for you to solve or to workout the best continuation. Computer analysis will also be considered. Some of these positions will come from actual historical games. Others will be composed endgame studies, but all the solutions will be relevant to the practical game. The new position will occur each SUNDAY and I will always be pleased to receive POSITIVE feedback about the positions and the analysis and I will try to acknowledge these where relevant.

Thanks to Steven B. Dowd, Antonio Senatore, Rainer Staudte, Henryk Kalafut, Jon Palmer, Gerard O'Reilly and Valdir Uchoa Jr.

White to play and WIN

FORSYTH NOTATION

:8/8/4P2R/bB6/6P1/8/5kpK/2n4b w - - 0 1:

Not too difficult this time. The main line and sub-variations are easy to follow. An important feature in this study is the underpromotion of the passed pawn to a Rook to avoid the stalemate trap. Black is threatening to promote his g-pawn so White's first move is fairly obvious:

1.Rf6+ Ke1

1... Ke3? 2.e7 Bc7+ 3.Kg1 and now Black will be at the mercy of the new Queen.

2.e7 Ne2!

The best shot. The Knight covers "g1" so the promotion threat is renewed.

2... Bc7+ 3.Kh3 g1Q (if 3... Kd1 4.e8Q g1Q 5.Rf1+ wins the Queen) 4.e8Q+ Kd2 and after 5.Qd7+ White will pick up a Bishop with check, or else mate quickly.

3.Bxe2 Bc7+

4.Kg1 ...

4.Kh3? g1Q 5.Rf1+ Qxf1+ 6.Bxf1 Bc6=;

4... Be5!

Black is threatening to win with..Bd4+ followed by promoting the g-pawn.

4...Bb8 5.Ra6 (if 5.e8Q Ba7+ 6.Kh2 g1Q+ 7.Kh3 Bg2+ 8.Kh4 Be3 9.Kh5 Qh2+ 10.Kg6 Qh6+ 11.Kf7 Bd5+ 12.Re6 Bxe6+=) 5...Be5 6.Ra4 (if 6.e8Q Bd4+ 7.Kh2 g1Q+ 8.Kh3 Kf2 9.Qf7+ Kxe2=) 6...Bd6 (or 6...Bc7) 7.Ra1+ Kxe2 8.e8Q+ wins.

5.Rf4! ...

In order to avoid the Bishop check White gives up the Rook.

5.Rf1+? gxf1Q+ 6.Bxf1 Bc6 =;

5... Bxf4

6.e8R! ...

White underpromotes to a Rook to avoid the stalemate trap. It is so easy to walk into this kind of trap when overconfidence or tiredness destroys concentration.

6.e8Q? Be3+! 7.Qxe3 stalemate;

6... Kd2

6...Bh6? 7.Bf3+ Kd2 8.Bxg2 Bxg2 9.Kxg2 winning.

7.Bf3! ...

The Bishop threatens to win the g-pawn. Ordinary Bishop moves would lead to a dangerous check on the a7-g1 diagonal.

7.Ba6? Bc7 8.Re6 Bb8 9.Re7 Bd6! -threatens Bc5+- 10.Rd7 (if 10.Re2+ Kd1 11.Rxg2 Bxg2 12.Kxg2=) 10...Ke1! 11.Rxd6 stalemate (if 11.g5? Bc5+ 12.Kh2 g1Q+ 13.Kh3 Bf3 winning)

7.Bb5? Bc7 8.Re6 Bb8 9.Ra6 Bf4 10.Ra3 Bc7 11.Ra6 Bf4=.

7... Be3+

8.Rxe3 Kxe3

9.g5 Kf4

Black has one more go to save the game but White is concentrating to the end.

10.g6 Kg5

11.g7 Kh6

12.g8R! wins.
